Title: Manufacture of single-crystal ferrite
Inventor: OSANAWA MASATO
IPC: C30B29/22
Filed: 1988-03-24
Abstract: PURPOSE:To obtain high-quality single-crystal ferrite by growing a ferrite single crystal by means of solid phase reaction by using a polycrystalline ferrite material in which specific amounts of SnO2 are allowed to enter into solid solution to effectively reduce residual blowholes and island structure. CONSTITUTION:The prescribed amount of SnO2 component is mixed with a powder mixture of ferrite material composed principally of F2O3, and the resulting mixture is temporarily calcined, crushed, formed, and then burned, by which a polycrystalline ferrite member in which SnO2 is allowed to enter into solid solution by 0.1% by weight, preferably >=0.5%, is obtained. This polycrystalline ferrite member is temporarily joined to a single-crystal ferrite member, after subjected to the mirror finish of contact surfaces and provided with inorganic acid (salt), and the joined members are heated up to a high temp., by which polycrystalline ferrite is formed into single crystal by means of solid phase reaction.

Title: Lens cleaning cartridge
Inventor: YAMAMOTO HIROSHI
IPC: G11B7/121
Filed: 1987-03-25
Abstract: PURPOSE:To automatically clean a lens of an optical means by only loading a cartridge into a device by constituting in such a manner that the lens is cleaned via an opening part of the cartridge main body by its cleaning member. CONSTITUTION:A cleaning cartridge 2 is inserted into an optical disk device, and a shutter 20 is opened and then the lens of an optical head is moved via the opening part 21 into contact with the cleaning member 26, so that the lens is hence cleaned through a cleaning liquid applicator part and a dryer part. Under such a circumstance, a triangular base 25 supporting the member 26 is supported axially by a supporting axis 24 to be unable to turn clockwise. When the lens is in its return process, the base 25 is turned counterclockwise and since the cleaning liquid applicator part can not be in contact with the lens, the lens will never pick up some dirt again. The shutter 20 is closed and the cartridge is delivered out. Consequently, an optical lens can be cleaned automatically by loading the cleaning cartridge only.

Title: Structure for recovering coal slag in coal burner
Inventor: MATSUBARA SEIICHI
IPC: F23J1/08
Filed: 1980-05-29
Abstract: PURPOSE: To facilitate the recovery of coal slag by providing a fused coal slag reserve chamber at the bottom of the coal burner from which high temperature coal burning gas is taken out to the side, contacting the diffused coal slag with air, and obtaining the solid state particles.  
     CONSTITUTION: The coal 2 and the air 3 are mixed with rotating blades 4 in the coal burner 1, and the high temperature burning gas 5 is generated. When the burning gas is flowed into a seed burning chamber 6, the burned coal slag 7 in the burning gas is separated into the slag reserving chamber 8 by changing the direction of said gas. When the diffused slag 7 which is reserved at the bottom of the slag reserving chamber 8 is flowed down to a slag solidifying chamber 15, it is solidified into particles whose diameters are several mmW10 and several mm by the injection of slag particle solidifying air 17 from a slag particle solidifying nozzle chamber 16. Adhesion of the slag particles 23 to the wall of the solidifying chamber 15 and to a separating valve 21 is avoided by the injection of slag adhesion preventing powder 18 at this time. The slag particles are recovered through the separating valve 22.

Title: Magnetic encoder
Inventor: MATSUMOTO HIDETOSHI
IPC: G01B7/00
Filed: 1991-04-03
Abstract: PURPOSE:To obtain a compact apparatus without any positional displacement at low costs by turning a coded multibit absolute position signal to a magnetizing pattern, and magnetizing the pattern in the rotating direction of one track of a rotary drum. CONSTITUTION:A magnetizing pattern 104 is formed in a track which goes round a magnetic drum 101, and each track is divided into 2<n> areas. Data of the absolute position, namely, absolute signal of (n) bits is magnetized in each area. Magnetoresistance (MR) elements 105 are arranged at positions corresponding to the magnetizing signals. For example, when n=3, the periphery of the track is divided into 8 areas, and a 3-bit signal is magnetized in the magnetizing pattern in each area. An absolute signal in the fifth area is 101, and the magnetizing pattern is NSSN. Tone magnetic field impressed to each MR element 105 is changed by the rotation of the rotary drum 101, which is converted to the change of tone resistance, and accordingly the absolute signal is output, whereby the absolute position is detected.

Abstract: PURPOSE:To eliminate a difference between right and left wheels in steering the rear wheels by making a turning angle of an input member different by a designated amount between on one side and on the other side with respect to a reference position by a turning angle changing means. CONSTITUTION:Though the rotation of a steering wheel is transmitted to an input shaft 14, bevel gears 84, 82 and a rotation applying arm 80, as the bevel gear 82 is disposed with a fixed amount (e) of eccentricity with respect to an axis l1, a point B of a ball joint 83 is turned with eccentricity so that even if the turning angles of the input shaft 14 on right and left are the same, the turning angle of a point A of a ball joint 75 is larger on the right side where the bevel gear 82 is eccentric with respect to a rotation reference position (theta=0) of the input shaft 14 than on the left side to correct the travel of a control rod. A control mechanism C controls a pulse motor 21 according to a car velocity, whereby a steering ratio is changed according to a car velocity. Thus, a different between right and left wheels in steering rear wheels can be eliminated.

Title: Pad device
Inventor: IMAMURA TATSUO
IPC: G11B17/34
Filed: 1985-04-04
Abstract: PURPOSE:To make a contact part hardly affected by worn-out powder by setting the part coming into contact with the information recording medium of a pad device to a shape including a part extending substatially in the traveling direction of the information recording medium. CONSTITUTION:Two approximately semi-cylindrical pads 22a and 22b are spaced and provided by the prescribed interval, and their both ends are formed round so that a magnetic disk 2 can travel smoothly. Thus, when a main magnetic pole 21a slides the magnetic disk 2, it is deformed to form the profile 30 of the sliding part, which is formed a laterally-long approximately elliptical shape in such a way as a contour line, and therefore the worn-out powder, etc., sent by the magnetic disk 2 is almost completely separated from the sliding part of a head 1 and transported to a down-stream side as arrows Y11 and Y12 show. Since a distance between the front end of the sliding part and the main magnetic pole film 21a is comparatively large, the worn-out powder, etc., hardly enter the sliding part of the main magnetic pole film 21a.
